Somaesthetics

 This note explains the method anchor behind the site: weakly bounded bodies matter as
 lived bodily conditions, not visual style alone.

In brief

 Somaesthetics treats the lived body as the medium of perception, action, and
 self-presentation. Boundary design therefore matters here as a question of felt bodily
 organization.

 The method page (https://mesmerprism.com/plasmatic-multitudes/project.html) applies that stance to boundary
 precision; this appendix keeps the short somaesthetic anchor available without
 making it a top-level route.

What the term means

 On this site, somaesthetics names a practical orientation: start from the lived body.
 The body is treated as a cultivatable medium of perception, action, and
 self-presentation rather than as a neutral container for visual effects
 (Shusterman (https://www.interaction-design.org/literature/book/the-encyclopedia-of-human-computer-interaction-2nd-ed/somaesthetics); Hook et al. (https://doi.org/10.1145/2598510.2598561)) .

 Introspection does not replace design. Design choices are evaluated by how they change
 felt bodily experience: attention, trust, effort, contact, containment, permeability, or
 relation.

Why it matters here

 Weakly bounded bodies become interesting once their edge is treated as part of embodied
 experience. A body that softens, diffuses, or becomes collective reorganizes where the
 body seems to begin and end, how it is held together, and how it meets others
 (Wagemans et al. (https://doi.org/10.1037/a0029333); Johansson (https://link.springer.com/article/10.3758/BF03212378); Glowacki (https://doi.org/10.3389/frvir.2023.1286950)) .

 The site uses boundary precision as a key term for what happens when the body's edge
 becomes a designed condition while coherence is still preserved.

Design consequences

 A somaesthetic framing leads to three recurring tests. First: does the transformation
 preserve enough coherence for ownership and trust? Second: does it change relation,
 action, or felt bodily meaning rather than merely adding ornament? Third: can the
 change be described, staged, and compared as a real design variable
 (Yee and Bailenson (https://doi.org/10.1111/j.1468-2958.2007.00299.x); Lecuyer (https://doi.org/10.1162/pres.18.1.39); Ho et al. (https://doi.org/10.1016/j.jpain.2021.10.009)) .

 That is the through-line connecting the overview, the method page, the pain essay, and
 the vocabulary guide. Somaesthetics clarifies why those tracks belong to the same
 argument.
